On precise, with a fresh install of ros-fuerte-desktop-full and ros-fuerte-openni-kinect, I still get this issue. I am running the latest ros openni_kinect version 1.5.4.0, I believe.

OpenNI version is 1.5.4.0.

Since there is no longer an openni_tracker 'tracker.launch' file, if I run the executable directly out of the bin directory:

EDIT:

I just tried the workaround posted by Mike Gao above, and it worked fine. So, not sure what the problem is with the built in version of NITE.
